Image correction for uncooled ("TECless") cameras

Market need

Image sensors produce background patterns that need to be corrected in every acquired image. In some sensor technologies, the dependency with temperature is so strong that payload developers have been forced to add temperature control systems to stabilize the temperature at specific setpoints.

While these type of solutions are effective, they have a remarkable impact in power, mass and volume. For small-satellite missions, adding temperature control can be infeasible or provide poor stabilization, which ultimately degrades image quality.

Proposed solution

We offer a new patented method that allows obtaining high quality images by correcting the background patterns of image sensors at any operational temperature, thus removing the need of including temperature stabilization systems in cameras where such systems were mandatory.

Cameras integrating this method can benefit from a significant reduction of power, mass and volume, as well as from simplified operational requirements.
